BERTRAND L. GEORGE, OF METI-IUEN, MASSACHUSETTS.

LAMP-GUARD.

Application filed July 26, 1915.

To all whom it may concern Be it known that I, BERTRAND L. GEORGE, a citizen of the United States, residing at Methuen, in the county of Essex and State of Massachusetts, have invented a new and useful Lamp-Guard, of which the following is a specification.

This invention relates to a guard for an incandescent electric lamp, and the principal objects of the invention are to provide a guard which in addition to protecting the lamp itself, extends entirely around the lamp socket and offers protection for the same throughout the entire length of the socket; to provide a construction in which the lamp socket is yieldingly held by the guard itself in position in the neck of the guard so as to hold the lamp in central posi tion and prevent motion of the guard longitudinally and yet permit of the insertion and removal of the socket by pressure in a longitudinal direction; to provide means for holding the socket in such form that when the socket is removed this means can be bent back and forth readily to adjust its gripping tension; and to provide a construction in which the guard is formed of wire and specifically of a series of wires arranged longitudinally and so constructed that when used on a key socket the key will slip into position in the guard between the wires when the lamp is moved into place longitudinally.

The invention also involves a yielding connection at the end of the guard for receiving the connecting wires and permitting the suspension of the guard in a yielding manner and also the provision of a stand in connection with the guard in which the lamp can be held in upright position.

Further objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings in which Figure 1 is a side view of a lamp guard constructed in accordance with this invention, and Fig. 2 is a similar view of a modified form.

In the form shown in Fig. 1 the guard consists of a wire frame A formed of longitudinal wires (1 arranged in a circle and connected together by two circular wires a and the guard is provided with an open end. These wires a are bent inwardly beyond one circular wire a so as to form the neck B concentric with the frame A and at Specification of Letters Patent.

the end thereof. The wires a are shown as arranged in pairs, certain pairs extending to the end of the neck B where they are secured together by a circular wire a at the end. Each alternate pair of wires a in this case are used for a different purpose. They are contracted inwardly so as to form a part of the neck, but they do not extend to the wire a but on the contrary are doubled over on themselves at a point part way between the ends of the neck. In other words, two of these wires are integral with each other and bent at a point u These wires that are bent at this point therefore form a projecting resilient tongue which can be bent back and forth to adjust its position. These tongues are provided with projections (1 extending inwardly for the purpose of engaging in a groove 0 in a lamp socket C. In the form shown in Fig. 1 this socket is shown as of the porcelain type. The lamp D is shown mounted in this socket. At the end of the neck B is a spring E which surrounds the conducting wires or cable, having a collar 6 for this purpose. This offers a means by which the guard can be held yieldingly so as to reduce the effects of any shocks to which it may be subjected.

It will be seen from what has been said that the lamp can be inserted in the guard by forcing it inwardly in a longitudinal direction until the projections (1* enter the groove 0 and that it is then held yicldingly but firmly in that position and although there is no danger of accidental displacement, yet it can be drawn out longitudinally. It will be seen also that the tongues a can be bent out or in to adjust their position and the degree of pressure which they put upon the socket. In the form shown three of these tongues are present and they hold the socket centrally and thus also hold the lamp in central position. The other end of the socket substantially engages the neck of the guard so as to prevent its getting out of alinement. It will be seen also that the wires 6 are so arranged that when the socket is being put into place the key 0 of the socket will slip in between two of the wires and move substantially to the end of the space between them.

In the form shown in Fig. 2 substantially the same principles apply, except that the wires of the neck B are secured at the end of the neck by contracting the wires and placing a ring 13 around the same to hold them in position and these wires are extended beyond this ring and then flare out to form a stand F on which the whole device can be supported. In this case also a metallic socket C is shown in which there is no groove around the same, but which is provided with a shoulder C and the tongues A are correspondingly shaped, the purpose being the same as in the other case.

Although I have illustrated and described only two embodiments of the invention and shown it as arranged for supporting only two kinds of lamp sockets, I am aware of the fact that many other modifications can be made in the invention and that it can be adapted for supporting lamp sockets of other shapes without departing from the scope of the invention as expressed in the claims. Therefore I do not wish to be limited in these respects, but

lVhat I do claim is:-

1. The combination with an incandescent electric lamp and socket, of a guard therefor comprising a wire frame adapted to surround the lamp and having a central contracted substantially rigid neck at one end constituting a complete cylinder terminating in a circular end wire so as to form a comparativcly rigid handle for manipulating it, and means for engaging thesocket and holding the socket centrally, whereby the lamp is held centrally in the frame and also forholdin'g the socket against longitudinal motion, said neck surrounding and protecting the socket substantially throughout its length.

2. The combination with an incandescent electric lamp and socket, of a guard therefor comprising a frame formed with a plurality of longitudinal wires arranged in a circle and adapted to surround the lamp, said wires being contracted 'at the end of the frame so as to form a cylindrical contracted neck, certain of said wires extending to the end of said neck and being secured at the end, and others of said wires terminating at a point between the end of the neck and the end of the body of the guard so as to form resilient tongues having projections thereon for engaging the lamp socket.

3. As an article of manufacture, a lamp guard comprising a frame having a body for receiving an incandescent electric lamp and formed with a series of longitudinal wires contracting at the end of the body to form a cylindrical neck or longitudinal continuation of said wires and provided with integral wire means located between the ends 7 of said neck for resiliently holding a lamp socket therein and preventing its moving out of position.

4. As an article of manufacture, a lamp guard comprising a cylindrical body having a plurality of longitudinal wires constituting its main portion, said wires being bent inwardly at the end of said main portion and extending longitudinally therefrom in the form of a cylindrical. neck for receiving a lamp socket, certain pairs ofsaid wires adjacent to each other being formed integrally with each other and doubled over within the circumference of said neck to form resilient tongues for holding the lamp socket therein, said tongues being provided with inward projections for engaging the lampsocket. 1 z y 5. As an article of manufacture, a wire lamp guard comprising a frame having a body for receiving an incandescent electric lamp having a cylindrical neck for holding a lamp socket therein, and a member on the end of said neck consisting of a spring wire coiled on itself for surrounding the con-- ductors connected with the socket.

6. As an article of "manufacture, a lamp guard comprising a frame having a body for receiving an incandescent electric lamp and formed with a series of longiti'idinal wires contracted at the end of the body to form a neck for holding a lamp socket therein, said longitudinal wires at the end of the neck be ing contracted atthe end of the neck and having "a ring surrounding them to hold them in position, and then flaring away from each other to form a base for supporting the guard. V A v 7. As an article of manufacture, a lamp guard comprising a frame having a body for receiving an incandescent electric lamp and formed with ase'ries of wires contracted at the end of the body to form a neck for holding a lamp socket therein, said neck being contracted at the end and thenfiaring away to form a base for supporting the guard.
